LVM默认使用4M的物理快,每一个物理卷被划分为称为PE(Physical Extents)的基本单元,具有唯一编号的PE是可以被LVM寻址的最小单元。 4,LV(Logical Volume,LV)逻辑卷 最终的VG会被切割成LV,这个LV也就是最后可以被格式化使用类似分区的东西。LV的大小与LV内的PE数量有关,LV的文件命名通常为【/dev/vgname/vname】...
Volume Group name. See lvm(8) for valid names. Tag Tag name. See lvm(8) for information about tag names and using tags in place of a VG, LV or PV. Select Select indicates that a required positional parameter can be omitted if the --select option is used. No arg appears in this ...
在恢复PV后,测试恢复VG,报出错误:“Cannot restore volume group VG with 1 PVS marked as missing”,而且此时pvs和vgs等LVM命令的输出全部为空。 对系统进行重启,重启后发现磁盘由原来的sdc-sdg变成了sdh-sdl,而扩容新增加的磁盘则从sdh-sdl变成了sdc-sdg,因此此次故障很大可能是系统出错导致新扩容的磁盘名称与...
物理卷PV(physical volume) :物理卷就是LVM的基本存储逻辑块,但和基本的物理存储介质(如分区、磁盘等)比较,却包含有与LVM相关的管理参数,创建物理卷它可以用硬盘分区,也可以用硬盘本身; 卷组VG(Volume Group) :一个LVM卷组由一个或多个物理卷组成 逻辑卷LV(logical volume) :LV建立在VG之上,可以在LV...
